The insurance expansion under the Affordable Care Act will cost $1.383 trillion over the next decade, more than $100 billion less than previous forecasts, the Congressional Budget Office said Monday. The nonpartisan budget office's report, an update to projections from February, shows the law costing less than in previous estimates in part because of the broad and persistent slowdown in the growth of health care costs. The news might come as welcome to Democrats who are struggling to defend the law in an election year. The reduced estimate is attributable mostly to the budget office's cutting its projections of federal spending for subsidies.

Study:Youthstarget of e-cigarette firms

An investigation by Democratic members of Congress into the marketing practices of electronic cigarette companies has found that major producers are targeting young people by giving away samples at music and sporting events and running radio and television advertisements during youth-oriented programs. The inquiry, led by Sen. Richard Durbin, D-Ill., and Rep. Henry Waxman, D-Calif., was conducted as the Food and Drug Administration prepared a major package of tobacco control rules that would place e-cigarettes under federal regulation. The new rules have been slow to appear, and lawmakers said they hoped their report, which came out Monday, might help speed their release.
